These improvements relate to refrigerators adapted to accommodate icevin the form of substantially large chunks or pieces for extracting. heatunits from' the hollow interior of the device. They have a relationfurther to that class of ice refrigerators adapted for what is known asoutside icing.

According to theoutside-icing method of refrigeration the practice hasbeen to install within the kitchen, pantry or whatever the inside roommay be, an ice box or refrigerator having two doors opening into the icecompartment, one at the front o f the device and the other at the back,cutting a hole through the wall of the building of about the size of therear door, putting a wooden casing in that opening, and hingingan'ordinary wooden door on the outside of the building to cover thatopening, the refrigerator being 2o finally positioned so that the reardoor there-v A of is in alignment with the wall opening.'

' f In such case the .iceman may lill the' ice chamber of therefrigerator by irst opening the door outside the building and thenopening the rear door of the refrigerator, thus opening a passageway tothe interior of the' ice chamber. o.

filling such refrig-` While the method of erators from the 'outside ofthe building has many advantages over the practice, also very common, ofcarrying the ice into the room and inserting it through the frontdoorway ofthe refrigerator, many serious objections obtain in theoutside-icing practice. Une' of the fact that the doors closing the icechamber are necessarily thick, v usually several inches through, sincethey contain 'heat insulating material such as cork ,for protecting therefrigerator openingagainst the entrance of heat units froml theoutside.

The arrangement of the rear-door is `such that when it swings into thepassageway.

leading through the wall of the building it'v necessarily occupies so'muchV ofthat space' as to limit vthe size ofthe piece of ice which maybepassed through the rear doorway of the ice box. To get Such a door o utof the way it would be necessary to swing it substantially parallel tothe rear surface-of the 'ice box, which isof course impossible owing tothe presence of the buildingl wall.- Another objection is in thefact'thatthe materials forming the .paageway to the hollow interior 'ofthe ice box 'soon Y me saturated with waterand accumulate dirt, giverise to the presence of vegetable growths,

vis done with smaller i926. serial no. 101,230.

cause the passageway materials and the wall y Y generally to rot, smellfoul, and be generally unsanitary, and, in addition, leakage of watertakes place between the inner surface of the building Wall and therefrigerator, causingthe plaster if present to become loose and fallaway or to become saturated and foul, and thus generally, in allcircumstances,

producing an unsanitary condition at a place impossible to clean' andremedy without re.-

moving the ice box or refrigerator as a whole or even the casing for theice passageway.

The present improvements have for some of their objects the overcomingof all of the disadvantages and objections mentioned or indicated as-inhering in the current means and method of outside icing ashereinabove set forth.' The improvements have further 4important objectsin` such .provisions as an increased ice capacity for a given size ofrefrigerator, meaning one which occupies a given space in the room,which increased capacity and the arrangement vof the space results inthe provisim of means for receiving a greater quantity of ice in asingle ieee of standard shape and size, say weig `ng one hundred pounds,the'lar er piece having a proportionately longer lif in the refrigeratorthan the same weight in rsmaller units, whereby such relatively smallrefrigerator may be iced to last several days whereas f otherwise dailyicing would be required, and resulting further in a more equalmaintenance of a low temperature-in thekrefrig- Aerator, and, for themost part; ay lower temperature, than will be had-@.xvhere the icing l Afurther object is to provide one feature ofv these improvements in theform of an attachment to'an ordinary icere'igerator whereby such reigerator may be made to accoodate, as one advantage, a very much Vasanother Aand important advantage, and which may be had substantiallyregardless an ordinary refrigerator having, we will say, a relativelysmall ice compartment ofdimensions ywhich do not contemplateanyparticular standard size of commercial ice, i

may be transformed according tothese im'- larger amount of ice, and toaccommodate, l

los

provements intoa device' which will accommodate aVone-hundred-pound.cake, thus saving much. expense to the icel merchant who lila makes thedeliveries,Y much inconvenience as 'I well as -e nse to the'owner oftherefrigerator, an withal, providing better results in refrigeration.Other objects and advantages will appear hereinafter. l

In the drawings Figure 1 is a fragmentary l perspective in front, topand side view of a refrigerator according to these improvements; Fig. 2is a horizontal section as o n the line 2--2 of Fig. 1; and Fig. 3 isavertical section as Von the line 3-3 of Fig. 1.

The fundamental refrigerator structure illustrated comprises a main bodyhaving a top v'vallV 9, vertical side walls 10, a rear wall 11V` (Fig.3), a front wall which will be denominated in general 12, and a bottomwall I 13 (Fig. 3). The front wall is ordinarily provided with, severaldoors opening into various compartments. Tn the drawings the door 12opens into the ice compartment 14 while the door 12h provides entranceto a-'compartment more particularly vadapted for food or other objectsand is usually provided with shelves.

With respect to the main refrigerator body there is nothing novelillustrated described or claimed'herein. It may be formed according toany well-known or approved con` struction as'to its general shape, thematerials used, the arrangement of compartments,

etc. InA practice the main body vwallsare composed partly of insulatingmaterial such as cork, and the ,doors are similarly in- Sulated.

1 We are here chiefly concerned with that art of the refrigerator havingmeans definmg a compartment for ice, which means will beunderstood inthe present instance as bevstantially the .ing the top wall 9, the upperportions of the side walls-10,y the door 12'* and the bottomr wall 13,(Fig. 3) usually covered with a sheet of zinc 15. The pipe -16 leadingfrom the downwardly-incline wall or support 15 is for carrying awaywater from the ice compartment.

The main. refrigerator body illustrated may be considered one whichoriginally was vprovided with a door at the rear end of the icecompartment in all material Vrespects like thedoor 12, and thatl suchVdoor was removed to rovide a relativelylarge opening-throng the rearwall 11 havlng'subcrossarea ofthe ice compartment.

-Roid withthe main body is an extension body avin a to wall 2Q, abottomwall 21,` and two si e wa 22, this extension `bod rectan arin sha,f open at bot,V ends, and o su'chlatera and verticaldimensions thatwhen normall appliedto the vrear wall 1,1;its hollow interior'24 will bein e ent with the Ahollow interior 14. Its

shown as being secured to the main body by four bolts or tie rods 25extending through the main body and through the extension body. Severalof these rodsare shown complete partly'by dotted lines in' Figs. 2 and3. A door 26 having a .hinge and latch means which ymay be considered inall re spects like those shown for the front door 12* in Fig. 1 holdsthe sealing closure 26 in readily removable relation the outer end Thisextension bod will ordinarily have suiiicient horizontal cpt-l1 to passthrough. the wall of a building, indicated at 27 by dotted lines,whereby access may be had to the hollow interior from the side of thewall opposite to that adjacent to-which. the main body of therefrigerator is placed.

The ice compartments of such refrigerators are usuall as zinc, and

lined with sheet metal such. have shown such lining 27 on the-innersurface of the extension body walls.- tension'bod will preferably beformed with a downwar ly and inwardly inclined slant so The bottom walls21 of this exthat thelining 27 has this slant also and is therebyadapted'to carry-water 'to the drip pipe 16. It will be noted furtherthat I or otherwise made as one body,

The hollow interior 24V constitutes at once a passageway for ice and anice compart- When the im ment, and forms with' the compartment '1 4aunitary compartment for ice. Y It will be noted that according to thisim rovement a relatively long cake o f ice will vaccommodated. -Forinstance, 'if the left-to-right width of the main body compartment beonly such as to accommodate the width of a one-v hundred-poundrectangular cake of ice, provision is thusxmade for 'the 'reception ofsuch a cake, andv thereby the lcapacity of therefrigerator is inc ffrom.normally that of say a' hun rdm th fifty d Ino 'arypraeti'o'e eunfpiece would extend longitudinally with the door 12* of Fig. 1,ywhereas with these improvementstheend `of a one-hundredpoun would bedirected toward the door 12.

number of fillings, the saving of expense to the ice merchantand .ofinconvenience to each, and that the present improvementsl make suchvpractice possible even with refrigerators of normally relatively smallsize; and in addition thereto the many objections to prior practices inoutside icing are over- COIIIG.

The drawings herewith show a refrigerator having an ice compartment atthe top. The invention may be embodied equally in such as: have the icecompartment at a side or in some other location. In the variousconstructions the extension body will be appropriately positioned toprovide the desired res ts. f

A valuable feature of the improvements is'.-

in the fact that the main bod of the refrigerator is not enlar d, and tat the resent advantages are ha through the uti ization of space outsidethe room in which the refrigerator is installed.

I contemplate as being included in these improvements such changes anddepartures Yfrom what is herein specifically illustrated ment, and aclosure for sealing the outer end of the extension body.
